Abstract
We demonstrate how to create maximal entanglement between two qubits that are encoded in two spectrally distinct solid-state quantum emitters embedded in a waveguide interferometer. The optical probe is provided by readily accessible squeezed light, generated by parametric down-conversion. By continuously probing the emitters, the photon scattering builds up entanglement with a concurrence that reaches its maximum after O(10^1) photo-detection events. Our method does not require perfectly identical emitters, and accommodates spectral variations due to the fabrication process. It is also robust enough to create entanglement with a concurrence above 99% for 10% scattering photon loss, and can form the basis for practical entangled networks.
